EAST BAY MUD is located in OAKLAND (ALAMEDA CO.). The primary water source type is Surface Water. This water system services 380,450 connections, and serves a total population of 1,379,750 individuals.
Of the 86 chemicals tested for in your water system, 17 chemicals were detected, and 12 average annual chemical findings exceeded their MCL, though this dos not necessarily constitute an MCL violation.
In the plot below, the Maximum Contaminant Level (MCL) is shown as a black horizontal dashed line. Each contaminant tested for in your water utility is represented by a vertical bar, and the height of the bar indicates the level of contaminantion of that sample. Any contaminant at or exceeding the black horizontal dashed line is a violation of the MCL, and values under the red line indicate safe drinking water.
Hover over the bars to see more information for each contaminant.
Although some contaminants were detected in your water system, 69 other chemicals were tested for and NOT detected, including: 1,1-DICHLOROETHANE, 1,1-DICHLOROETHYLENE, 1,1,1-TRICHLOROETHANE, 1,1,2-TRICHLORO-1,2,2-TRIFLUOROETHANE, 1,1,2-TRICHLOROETHANE, 1,1,2,2-TETRACHLOROETHANE, 1,2-DICHLOROBENZENE, 1,2-DICHLOROETHANE, 1,2-DICHLOROPROPANE, 1,2,4-TRICHLOROBENZENE, 1,3-DICHLOROPROPENE (TOTAL), 1,4-DICHLOROBENZENE, 2,3,7,8-TCDD (DIOXIN), 2,4-D, 2,4,5-TP (SILVEX), ALUMINUM, ANTIMONY, ARSENIC, BARIUM, BENTAZON, BENZENE, BERYLLIUM, BROMIDE, CADMIUM, CARBON TETRACHLORIDE, CARBONATE ALKALINITY, CHROMIUM (TOTAL), CIS-1,2-DICHLOROETHYLENE, COPPER, CYANIDE, DALAPON, DCPA (TOTAL DI & MONO ACID DEGRADATES), DICAMBA, DICHLORODIFLUOROMETHANE (FREON 12), DICHLOROMETHANE, DINOSEB, ETHYL-TERT-BUTYL ETHER, ETHYLBENZENE, FOAMING AGENTS (MBAS), HYDROXIDE ALKALINITY, IRON, LEAD, M,P-XYLENE, MANGANESE, MERCURY, METHYL-TERT-BUTYL-ETHER (MTBE), MONOCHLOROBENZENE, NICKEL, NITRATE (AS N), NITRATE + NITRITE (AS N), NITRITE (AS N), O-XYLENE, PENTACHLOROPHENOL, PICLORAM, SELENIUM, SILVER, STYRENE, TERT-AMYL-METHYL ETHER, TERT-BUTYL ALCOHOL, TETRACHLOROETHYLENE, THALLIUM, TOLUENE, TRANS-1,2-DICHLOROETHYLENE, TRICHLOROETHYLENE, TRICHLOROFLUOROMETHANE, TURBIDITY, LABORATORY, VINYL CHLORIDE, XYLENES (TOTAL), ZINC.

If a contaminant has an exceedance of 999%, this indicates a detection for which the MCL is 0. Any number divided by 0 is infinite, thus it is assigned an arbitarty large value to indicate exceedance.
